Finally going to replace the stock (P.O.S.) headunit with a double-DIN aftermarket unit. THE most valuable feature to me is a good-sounding (for both me and the caller) Bluetooth option to connect to my iPhone. I'm not going to stream music from the iPhone using Bluetooth, just make calls (I'll connect my iPod using a cable for that). Anyone have a recommendation that won't leave me sounding like I'm in a tin can? I need some quality for business calls. Thanks.

Check out the pioneer premier fh-p800bt. Pretty inexpensive and bluetooth sounds great. I have an iphone and once the mic was placed on the drivers side A pillar and facing me, there are no complaints. FYI, if you get a double DIN I'd recommend a black metra. Tried the grey and it looked a little cheesy. Black looks good and the metra uses the factory metal brackets so it's solid as can be in the dash.

The only negative with the pioneer premier fh-p800bt is the blue lighting. I'm getting use to it but wish it had the orange option to match the rest of the truck.

I learned a little more from a local shop. The owner claims Parrot has the best BT performance. Both Pioneer and Kenwood use Parrot for their BT functions, not sure if any others do. Also said that every year the quality improves, so avoid the older models.

Thanks for the recommendations. Leaning toward the AVIC-Z110BT. They sure are proud ($$$) of that thing.
